[R] Log-transform and specifying Gamma

[Peter Minting]

Dear R help,
I am trying to work out if I am justified in log-transforming data and specifying Gamma in the same glm.
Does it have to be one or the other?
I have attached an R script and the datafile to show what I mean.
Also, I cannot find a mixed-model that allows Gamma errors (so I cannot find a way of including random effects).
What should I do?
Many thanks,
Pete
